Lesson 4 • Mites and Mange Conditions

Examines Sarcoptes, Demodex, Psoroptes, and Chorioptes causing mange in animals. Connects mite biology to skin lesion patterns and diagnostic approaches.

Lesson 1 • Blood and Tissue Parasite Diagnostics

Examines blood smear preparation, buffy coat technique, and tissue impression smears. Connects smear findings to hemoparasite and tissue protozoan identification.

Lesson 2 • Molecular and Immunological Diagnostics

Introduces PCR, ELISA, and immunofluorescence assays for parasite detection. Evaluates sensitivity, specificity, and practical application in veterinary settings.

Lesson 3 • Fecal Examination Methods

Covers direct smear, flotation, sedimentation, and Baermann techniques. Connects method selection to target parasite density and morphology.

Lesson 4 • Larval Culture and Identification

Covers coproculture methods and infective larval identification to genus and species. Links larval morphology to targeted anthelmintic selection.

Lesson 1 • Gastrointestinal Parasitism and Disease

Examines protein loss, villous atrophy, and abomasal pathology caused by GI parasites. Links worm burden thresholds to production losses and clinical deterioration.

Lesson 2 • Neurological and Reproductive Parasitism

Covers Neospora-induced abortion, Parelaphostrongylus neurological migration, and Toxoplasma encephalitis. Connects parasite migration routes to neurological deficits.

Lesson 3 • Mechanisms of Parasite Pathogenesis

Covers mechanical damage, nutrient competition, toxin production, and immune-mediated injury. Provides the pathophysiological basis for interpreting clinical and necropsy findings.

Lesson 4 • Hepatic and Biliary Parasitism

Examines liver fluke-induced cholangitis, fibrosis, and black disease predisposition. Links hepatic damage to biochemical and production consequences.

Lesson 1 • Ectoparasiticide Drug Classes

Covers organophosphates, pyrethroids, isoxazolines, and macrocyclic lactones for ectoparasite control. Links formulation type to application method and residue considerations.

Lesson 2 • Drug Residues and Food Safety

Examines withdrawal periods, maximum residue limits, and extra-label drug use regulations. Connects pharmacokinetics to food safety compliance in production animals.

Lesson 3 • Treatment Protocol Design

Covers dose calculation, route of administration, and treatment timing relative to parasite life cycle. Builds skills for designing species-specific treatment plans.

Lesson 4 • Anthelmintic Drug Classes

Covers benzimidazoles, macrocyclic lactones, imidazothiazoles, and amino-acetonitrile derivatives. Links mechanism of action to spectrum of activity and target parasite groups.
